In my Mongoose script I write:
mongoose.connect('mongodb://localhost/mydb');
But currently there is no mydb database in Mongo. Will this create mydbif it doesn't already exist?

Create a New Database : You can create a new Database in MongoDB by using “use Database_Name” command. The command creates a new database if it doesn't exist, otherwise, it will return the existing database. you can run this command in mongo shell to create a new database.
Unlike SQL, where we need to create a database, tables and then insert the values manually, MongoDB creates the database automatically. You just need to save a value in the defined collection with the preferred name. You don't even have to mention that you want to create a database.
exports = mongoose. model('User',{ id: String, username: String, password: String, email: String, firstName: String, lastName: String }); It will automatically creates new "users" collection.
The command mongoose.connect('mongodb://localhost/mydb'); will indeed create the database mydb if it does not exist.
It will also create any collections you use in your app if they do not already exist in a similar fashion.
